Environmental Science in Today’s World Essay

serviceman so dominate todays world that there is no ecosystem on earth that has non been influenced to a greater or lesser degree of military personnel activities. And, as long as humans carry on on earth, such influence will not end. Sustainability will be on learning to channel our app arnt movements so that we play a commanding supporting use of erects and services as opposed to a destructive role toward ecosystems (Nebel & Wright, 1993). Environmental risk is a reality of todays world.The seemingly endless supply of synthetic chemicals, consumer goods, energy, and waste create in the buff risks through chemical contamination, pollution, and environmental degradation. Environmental disasters such as chemical spills or explosions threaten millions of people living in the vicinity of manufacturing or storage facilities. The uncertain risks of global warming and ozone depletion loom ahead. A rally factor of environmental risk is that it is usually involuntary.People do not choose to ingest chemical pollutants such as pesticides or industrial solvents in their food and water, to undergo workplace exposures to dangerous chemicals, to breathe colly air, or to experience radiation exposure from nuclear fallout or faulty nuclear power plants. These environmental risks pose a unmatched problem to regulators charged with protecting the general wellness. Limited information whitethorn be available on the health effects of these risks. Consequently, in an effort to protect the publics health, various government agencies study these potential drop hazards to determine the level of risk they pose.This effort to understand these risks, and to quantify their tinct on human health, is the field of risk analysis (Moore, 2002). The scale of human occupation and transformation of the environment is now truly global. The adverse health effects of this ignorance may have been limited, as the environmental damage was on a local scale. However, in todays world o ur activities are having an impact at a global scale, and global environmental mixture will become a major theme in public health research, social policy and development, and political advocacy in the twenty-first century.The conceptualization of the environment as a global public good for health should go some way not only in increasing an appreciation for this heritage and dependency, but should also enhance the porthole between research and policy. This increased awareness and interface between come across stakeholders might lead to effective action to ensure a sustainable future for current and future generations (Hester & Harrison, 2002).
